Session reliability

Citrix introduces the session reliability feature to all supported Linux platforms. Session reliability is enabled by default.

Session reliability reconnects ICA sessions seamlessly across network interruptions. For more information about session reliability, see Auto client reconnect and session reliability.

Note: Data transmitted through a session reliability connection is in plain text by default. For security purposes, We recommend that you enable TLS encryption. For more information about TLS encryption, see Secure user sessions using TLS.

Configuration

Policy settings in Citrix Studio

You can set the following policies for session reliability in Citrix Studio:

• Session reliability connections
• Session reliability timeout
• Session reliability port number
• Reconnection UI transparency level

For more information, see Session reliability policy settings and Auto client reconnect policy settings.

Note: After setting the Session reliability connections or Session reliability port number policy, restart the VDA service and the HDX service, in this order, for your settings to take effect.

Settings on the Linux VDA

• Enable/disable the session reliability TCP listener

By default, the session reliability TCP listener is enabled and listening on port 2598. To disable the listener, run the following command.

/opt/Citrix/VDA/bin/ctxreg update -k "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\WinStations\cgp"   -v  "fEnableWinStation" -d "0x00000000"
